A new young mother has opened a cloth diaper service. She is interested in simulating the number of diapers required for a one-year- old. She hopes to use this data to show the cost-effectiveness of cloth diapers. The table below shows the number of diapers demanded daily and the probabilities associated with each level of demand.

Daily Demand	Probability	Interval of Random Numbers
5	0.30	01-30
6	0.50	31-80
7	0.05	81-85
8	0.15	86-00

what is the cumulative probability if the demand is less than or equal to 7?
